To all wlimle it may concern.-

Be it known that l, JAGOB WEAVER, of Tipton, in the count-yet Cedar and State of Iowa,

have invented" a new and Improved Stovelipe Jolnt, of which the following is a specification: 7

In the accompanying drawing, Figure 1 rcp resents a fron t elevation of my adj ust'ablestovepipe joint; Fig.2, atop view of the same; and Fig. 3,,a, detail vertical section, on the line 0 c ot'Fig.2,of the Connecting-flanges ot' the joint.

Similar letters of reference indicate corresponding parts.

l'he object of my invention is to construct a revolving stove-pipe,which may be adjusted or twisted to any desired position to be used without delay on putting up the stove, avoid ingthereby the annovanee arising t'rom badlytitting or incompletelvarranged joints. The invention will be first, iullydescrihed and then clearly pointed out in the claim.

in the drawing, A represents the three tir bular pieces forming the stove pipe or elbow. The are cut ot a cylindrical tube, of suitable melal b v interseet'ing' the same. under a suitable angle to its axis. 'lhe upper and lower pieces A Form the connection with the pipes to stove and chimney, and are provided along the elliptieal periphery of the sections with on twardlyproieeting flanges (1, extending in thelilaneot the section. The middle piece 1\ is similarly providedwith flanges I), soldered or Iivetedto it. The llanges u and I) are of circularshapaaml extenu therefore farther from pieces A in the direction of the shorter .axis of the elliptical periphery than in the di-.

rcction of the longer axis of the same. The flanges b are slightly larger than flanges a,

and have rectangular rims d, which embrace wholly flanges a Flanges b are also provided with three or more projecting lugs, e, which,

are screwed, riveted, or otherwise connected I to similar lugs c of coupling-rings B, made of suitable material. These rings B are placed on the side of flange a'not embraced by flange b, and form, in connection with it, a strong and simple coupling'ot' the pieces A. 'Bymeans' ot' a set-screw and washer-plate, 0, pieces A may be tired into any position to which. they are turned, producing;thereby a. cylindrical elbow .or twisted shape of the joint. By placing a suitable packing between the ring it and
